How to Make The Cake Mix Doctor Peanut Butter Brownies

  1. Preheat oven to 350°F (175°C). Place rack in the center of the oven. Grease and flour a 13x9 inch baking pan.
  2. In a large bowl, combine 1 box (15.25 oz) fudge brownie mix, 1 cup creamy peanut butter, 1/2 cup (1 stick) unsalted butter, softened, and 2 large eggs.
  3. Beat with an electric mixer on low speed for 1 minute, then scrape down the sides of the bowl.
  4. The mixture will be thick. Set aside about 1 1/2 cups of the batter for the topping.
  5. Spread the remaining batter evenly into the prepared baking pan.
  6. In a medium microwave-safe bowl, combine 1 cup semi-sweet chocolate chips and 1/2 cup sweetened condensed milk.
  7. Microwave on high for 1 minute, then stir in 1 teaspoon vanilla extract. Continue stirring until the chocolate is melted and the mixture is smooth and creamy.
  8. Pour the chocolate mixture evenly over the brownie batter in the pan.
  9. Dollop spoonfuls of the reserved brownie batter over the chocolate layer. Swirl gently with a knife or toothpick for a marbled effect.
  10. Bake for 28-32 minutes, or until the edges are set and a toothpick inserted into the center comes out with moist crumbs.
  11. Let the brownies cool completely in the pan before cutting into bars.
